【问题描述】：

在Struts2中，是否可以同时在Action类中实现validation xml（ActionClass-method-validation.xml）和validate方法。

我在问，因为在我的情况下不会调用此验证 xml。

【解决方案1】：

希望您已创建正确的规则文件 actionname-validation.xml（注意，actionname 区分大小写）并将其保存在与 Action 类相同的包中。

另外，如果您没有配置默认拦截器，请在特定操作标记内的 Struts.xml 中添加验证拦截器。

<action name="welcome"  class="com.abc.web.WelcomeAction">
<interceptor-ref name="validation" />
<result name="success" >hello.jsp</result>
</action>

有关验证框架的更多详细信息，请参阅 http://struts.apache.org/2.0.14/docs/validation.html 和 http://java.dzone.com/articles/struts2-tutorial-part-37
